What is the garchx package?
- AbstractThegarchxpackage provides a user-friendly, fast, flexible, and robust framework for the estimation and inference of GARCH(p,q,r)-X models, where p is the ARCH order, q is the GARCH order, r is the asymmetry or leverage order, and ’X’ indicates that covariates can be included.
What is the rgarch package?
- This package is part of what used to be the rgarch package, which was split into univariate (rugarch) and multivariate (rmgarch) models for easier maintenance and use, both of which are now hosted on CRAN (stable) and bitbucket (development).

What is the difference between garchx and rugarch?
- Another salient feature is how much fastertseriesis relative to the other packages. This is particularly striking for the GARCH(2,2), where the second-fastest package –garchx– is about 5 to 6 times slower, and the slowest package –rugarch– is about 28 to 30 times slower.
